In the complex operation system of the power plant, the manual operating mechanism of the shaft output valve 830W-D-2234TT is like a precise and critical “valve heart”, and the long-term vibration environment is like a potential “double-edged sword”, which always threatens the normal operation of the gears in the manual operating mechanism, resulting in wear or jamming. These problems not only affect the precise control of the valve, but also may cause serious chain reactions to the stable operation of the entire power plant. Therefore, in-depth discussion on how to prevent gear wear or jamming is of vital importance to ensure the safe and efficient operation of the power plant.

1. Analysis of the mechanism of vibration on gear wear and jamming

The sources of vibration in power plants are wide, including mechanical vibration during equipment operation, impact vibration of fluid in pipelines, and slight vibration of the external environment, which will be transmitted to the manual operating mechanism of the shaft output valve 830W-D-2234TT.

For gear wear, vibration will cause additional impact force and alternating stress in the meshing process. This irregular force will destroy the oil film on the gear surface and aggravate the wear of the tooth surface. Under long-term action, the tooth surface will wear unevenly and the tooth shape will change, resulting in a decrease in gear transmission accuracy and affecting the accuracy of valve operation. At the same time, vibration may also cause micro-vibration wear of the gear. The tiny relative movement generates friction heat between the tooth surfaces, further accelerating the wear and fatigue peeling of the material.

As for the problem of gear jamming, vibration will cause the parts of the manual operating mechanism to displace or deform. When the vibration causes a slight change in the center distance of the gear, the meshing clearance of the gear will be abnormal. If the clearance is too small, the gear will easily get stuck during operation and cannot rotate smoothly. In addition, vibration may also make it easier for impurities to enter the gear meshing area. These impurities will act as abrasive particles, further aggravating the jamming problem, and even causing the gear to bite, making the manual operation function completely ineffective.

2. Optimize installation and fixing methods

To effectively prevent gear wear or jamming, we must first start with the installation link. When installing the manual operating mechanism of the shaft output valve 830W-D-2234TT, ensure that the installation foundation is firm and flat. Use high-strength anchor bolts to tightly fix the base of the operating mechanism to the foundation to reduce the displacement caused by vibration. At the same time, set a shock-absorbing pad between the base and the foundation, such as a rubber shock-absorbing pad or a spring shock absorber, which can effectively absorb and isolate vibration transmission.

For the gear assembly inside the manual operating mechanism, the installation accuracy of the gear must be strictly controlled during the installation process. Ensure that the center distance, tooth side clearance and other parameters of the gear meet the design requirements. Use advanced installation technology and measuring tools, such as high-precision micrometers and dial indicators, to accurately adjust the installation position of the gear. In addition, when assembling the gear, ensure that the axial positioning of the gear is accurate to prevent the axial movement of the gear due to vibration during operation, which affects the meshing quality.

3. Strengthen lubrication management

Good lubrication is a key factor in reducing gear wear and preventing jamming. It is crucial to choose the right lubricant. For the long-term vibration environment of the power plant, a lubricant with a high viscosity index, good anti-wear performance and extreme pressure performance should be selected. For example, a lubricant containing sulfur-phosphorus extreme pressure additives can form a tough protective film on the surface of the gear to effectively resist the high load and impact force caused by vibration.

Regular lubrication maintenance is an important measure to ensure the lubrication effect. Formulate a scientific and reasonable lubrication cycle, and regularly add grease or replace lubricating oil to the gears according to the operating conditions of the power plant and the equipment manual. At the same time, during each maintenance process, the lubrication system should be checked to ensure that the lubricating oil path is unobstructed and there is no blockage. In addition, attention should be paid to the cleanliness of the lubricating oil to prevent impurities from mixing into the lubricating oil. A high-precision filter can be installed in the lubrication system to filter out tiny particle impurities.

4. Strengthen protection and sealing

Setting up a protective device for the manual operating mechanism of the valve 830W-D-2234TT can effectively reduce the intrusion of external dust, water vapor and other impurities. A protective shell can be installed outside the operating mechanism, and the protective shell should have good sealing and dustproof performance. For example, a protective shell made of stainless steel can not only prevent dust from entering, but also resist a certain degree of corrosion. At the interface of the protective shell, a rubber seal is used for sealing to ensure the protection effect.

For the sealing of the gearbox, ensure that the sealing performance is good. High-quality oil seals and sealing gaskets are used to prevent lubricating oil leakage and external impurities from entering the gearbox. Check the status of the seals regularly. If the seals are found to be aged or damaged, they should be replaced in time. In addition, a breathing valve is set on the gearbox to balance the pressure inside and outside the box and reduce the risk of seal failure caused by pressure changes.

Through a series of comprehensive measures such as optimizing installation and fixing methods, strengthening lubrication management, strengthening protection and sealing, and implementing real-time monitoring and intelligent early warning, the impact of vibration on gears can be effectively reduced, the service life of gears can be extended, and the stable and reliable operation of the manual operating mechanism can be ensured, providing a solid guarantee for the safe and efficient production of power plants.
